Choosing a wood species is very much a matter of taste. Some people prefer light, blonde-coloured timbers whilst others prefer darker, more exotic tones.
Consider the overall effect that you want to achieve. Contrasts often work and dark floors can look particularly stunning with light toned walls, and visa-versa.
For specific guidance, contact a professional wood flooring specialist.
Also, bear in mind the function of the room in which you're installing the floor; some timbers are harder than others and may be more suitable for high traffic areas.
